Cotyledon, seed leaf within the embryo of a seed. Cotyledons help supply the nutrition an embryo needs to germinate and become established as a photosynthetic seedling and may themselves be a source of nutritional reserves or may aid the embryo in metabolizing nutrition stored elsewhere in the seed.
Cotyledon is the significant part of an embryo present within the seed. There are two different types of cotyledons. Explore more about cotyledon, at BYJU’S.
Cotyledons may be ephemeral - lasting only days after emergence, or persistent - enduring at least a year on the plant. The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food-reserves of the seed.
Nov 21, 2023 · Cotyledons provide nutrients to the developing embryo within a seed until the plant is established and is able to produce its own sugars via photosynthesis. It is important to note that not all...
Anatomy of Cotyledons. Cotyledons, also known as seed leaves, are the first leaves to emerge from a germinating seed. They are part of the embryo within the seed and can be found in the embryonic axis. Cotyledons can vary in shape, size, and number depending on the plant species.
Dec 2, 2022 · What is a cotyledon? It is the embryonic part of a seed which stores fuel for further growth. Some cotyledons are seed leaves which fall off the plant within a few days. These cotyledons on plants are photosynthetic, but there are also hypogeal cotyledons which remain under the soil.
May 14, 2023 · A cotyledon is a part of a plant seed. More specifically, a cotyledon is part of the seed embryo and plays a crucial role in a plant’s germination process. Once a plant seed sprouts and begins to grow, the cotyledon pops up and opens, becoming the plant’s first leaves. Cotyledons are not true leaves, which can cause confusion in novice ...
